Subject: [PATCH 4.4 107/159] fbdev: Remove unused SH-Mobile HDMI driver
From: Geert Uytterhoeven <geert+renesas@...der.be>
commit 34280340b1dc74c521e636f45cd728f9abf56ee2 upstream.
As of commit 44d88c754e57a6d9 ("ARM: shmobile: Remove legacy SoC code
for R-Mobile A1"), the SH-Mobile HDMI driver is no longer used.
In theory it could still be used on R-Mobile A1 SoCs, but that requires
adding DT support to the driver, which is not planned.
Remove the driver, it can be resurrected from git history when needed.
